SDF Routines Obsoleted in IDL 5.3

HDF_DFSD_* routines have been obsoleted in IDL 5.3.

What is DFSD and Why Are We Obsoleting It?

DFSD is an SD (Scientific Data Model). DFSD is the older, single-file SD form. The newer SD format, MFSD, is referred to in the IDL API as HDF_SD_*. New IDL code should use HDF_SD_* routines rather than HDF_DFSD_* routines.

Version HDF4.1r2 of HDF has obsoleted the DFSD interface, somewhat forcing us to do so as well. IDL 5.3 uses HDF4.1r3 (Version 4.1, revision 3). It is recommended that users convert their old HDF files to the 4.1r3 format.

The following HDF routines have been obsoleted in IDL 5.3.
